Abstract

By developing a chalcogenide memory element that can be operated at low writing current, we have demonstrated the possibility of high-density phase-change random access memory. We have investigated the phase transition behaviors in function of various process factors including contact size, cell size and thickness, doping concentration in chalcogenide material and cell structure. As a result, we have observed that the writing current is reduced down to 0.7mA.
